The 'Forget You' hitmaker has been a judge on the US version of the singing contest on the first three series, before returning on the fifth series last year, but has now decided to step back to focus on other TV projects.

Speaking on the 'The Ellen DeGeneres Show' - which airs on Wednesday (02.19.14) - he said: "I'm not coming back guys.

"I'm going to continue my relationship with NBC. I have a television show development deal with them as well and hopefully some other talk show opportunities for later in the year.

Shocked by his revelation, Ellen replied: "Oh, you're not coming back at all? I did not know that!"

CeeLo is hoping to take some time to focus on his music and is excited about the release of his next album 'Girl Power', which is due out between February and March.

He added: "I just want to ... I don't want to wear out my welcome there. "You know what I'm saying. I have so many other things that I want to do. I haven't released an album in four years. I'm almost done with my album."

'The Voice's sixth season kicks off on February 24 with Shakira, Usher, Blake Shelton and Adam Levine on the judges panel.
